If a 'Newbie' anyway, better to learn the 'good' way and have a look at the netlist file!

EDIT: Just had a look at the LTSpice schematic editor and it does not seem to be able to higlight nodes. If you look at the netlist file (open the file using a text editor or let LTSpice show the netlist via the menu entry), you will find a line for each component:

Node 23 seems to be the emitter of Q7. When I tag the opamp line this node changes to from node 23 to node 24 !

This hints at a problem with the schematic editor / user interface - the netlist is determined by the schematic and does not change unless you change the schematic, i.e. not by clicking/tagging anything. Looks as if the tagging function randomly selects wrong nodes when clicking anything.

Definitely looks like a bug to me!!! It shows 7V when I hover over any point on that line. If I click on the lower part it puts 7V If I then click on the upper part, it puts 34mV (and the lower one changes from 7V to 34mV.

I deleted the two tags and did it again. this time it started with 7V and then when I clicked above it got -652mV... (for both places) very odd!!

and yes node 023 is the emitter of Q7!!

I tried dragging R29 to show that there were no breaks in the line, and now I cannot get a tag anywhere on that non-straight line it just gives ???! I suspect that there is a bug in the interface that is not properly picking up the co-ordinates of the mouse when you click to add the tag. It is certainly reproducable with the model you have attached though, so should make things easy to report if you want to do a bug report!

edit: I did it one more time and this time it was -2.32V and node 022 which I think should be the -ve input of the opamp which it is now showing at 7V and node N032!! It seems this time it has swapped the negative input and the output!
